The SCS22 shaft collar is engineered for the 22 mm shaft diameter — particularly common in European motor and gearbox catalogues, appearing as the output shaft of IEC frame 80 motors, compact helical-bevel gearboxes, and many imported material-handling drives. The outer diameter steps up to 45 mm, providing a generous 11.5 mm wall per side.
The 6 mm keyway (available to order) aligns with the DIN 6885A 6×6 parallel key standard common to European drive engineering, allowing the SCS22 to be deployed directly against motor shafts that already carry a factory-machined keyway — eliminating shaft rework in retrofit applications where disassembly carries a high labour cost.

🇺🇸 European IEC80 Motor Standard
22mm is the IEC frame 80 output shaft diameter — SCS22 is the direct-fit collar for Europe's most popular motor frame class.
▲ 45mm OD: Shared with SCS25
Standardise your 45mm housing bore across 22mm and 25mm shaft designs — reduce casting and tooling variants.
📈 High Vibration Resistance
Larger 45mm OD provides more friction contact area vs 40mm OD collars — proven resistance to vibration-induced creep.
⚙ 6mm Keyway, DIN Factory-Standard
Engages existing motor shaft keyway without rework — ideal for retrofit and maintenance collar replacement.
IEC 80 frame motors — widely installed in European-designed process machinery — output on 22 mm shafts. An SCS22 behind the motor-side coupling half prevents the coupling from walking toward the motor bearing housing under thrust reversal forces of start-stop controlled drives.
Vibratory bowl feeders and tray conveyors used in assembly automation use eccentric-mass drives on 22 mm shafts. The SCS22's large contact surface resists the combined axial and radial forces generated by out-of-balance vibration mechanisms through billions of vibration cycles.
Institutional washing equipment uses drum shafts at 22 mm in many European-designed machines. The aluminium SCS22 provides a lightweight, corrosion-resistant axial stop, and its anodised surface treatment provides additional galvanic isolation in high-humidity wash environments.
The SCS22 occupies the lower end of the 45 mm OD bracket shared with the SCS25. This shared outer dimension allows engineers to use a single 45 mm nominal housing bore for both 22 mm and 25 mm shaft sizes — useful standardisation in multi-line plants where shaft sizes vary by line capacity but housing castings are common. For high-vibration environments such as vibratory feeders or industrial washing machines, the SCS22's larger 45 mm OD provides proportionally larger contact friction surface compared to the 40 mm OD SCS20. Contact EP for vibration-specific application support.
Yes, though more common in European-designed machinery. It also appears in some Japanese and Korean industrial equipment. In Chinese domestic machine design, 20 mm and 25 mm are more prevalent, making the SCS22 most in demand for import equipment maintenance.
Yes. All three collars in the 40–45 mm OD bracket (SCS18, SCS20, SCS22) use M5 socket-head cap screws — a single hex key size services all three in a mixed-shaft machine.
The keyway is machined to JS9 tolerance (width) to pair with a standard 6×6 DIN 6885A parallel key in h9 tolerance. The resulting fit is a sliding fit that allows key installation without a press while maintaining positive engagement under torque.
Yes. Anodised and hard-anodised finishes are available on request. Hard anodising (25–50 μm) provides corrosion protection and improved surface hardness for abrasive environments.
